cover, so that the same may be held taut upon and around the tire.

A special object of the improvement is to avoid the use of buttons or like fastening means, which can only be secured at fixed intervals, by the use of a cam clamping fastener secured to the edge of one overlapping end of the cover,`and adapted to engage and clamp at any place upon the corresponding edge portion of the other overlapping end of the cover.

Such edge engaging and clamping means may be in the form of a metal base plate having an L-flange along one side forming an abutment jaw spaced from the base plate; and by providing a central opening in the base plate and pivotally mounting a lever upon the other side of the plate, providing a flat cam tongue operable through the opening toward and from the abutment 1aw. 85 The base plate is secured to the edge portion of one overlapping end of the cover, and the corresponding edge portion of the other end of the overlapping cover is entered between the secured edge portion and the abutment jaw, where it may be adjusted endwise and then clamped in place by the cam tongue.

The invention is illustrated in the accompanying drawings, forming part hereof, in which- Figure 1 is a side elevation of a cover as secured upon a tire:

Fig. 2, a fragmentary enlarged elevation of the overlapping ends of the cover, showing a plan of one edge fastener;

Fig. 3, a longitudinal section of the fastener showing the overlapping edges of a cover secured together by the fasteners, as on line 3 3. Fig. 2;

Fig. 4, a fragmentary cross section of the same, omitting the overlapping ends of the perspective view of the throughout the several figures yof the drawings.

The tire cover 1 may be made of oil cloth or other suitable fabric in the forml of an annular sleeve or casing, split around its inner side to form edges2, to envelop the tire casing proper when it is placed circumferentially thereon, 'and having a sufficient length to lit tires of a number of sizes by an overlapping of its lends 3 and' 3" to a greater or less extent.

The body 4 of the fastener may be an elongated fiat plate of metal or the like, having apertures 5 in'each end for rivets 6 preferably used for securing it to the edge portion of one of the ends of the cover. A fiange 7 extends from one edge of the plate inward past the secured edge of the cover,

whence an L-tongue or plate 8 extends inward substantially parallel with the body of the fastener and at a spaced interval therefrom.

A central opening 9 is provided in the base plate, as by cutting and striking outward ears 10 along each side of the opening, in which ears may be provided bearings 11 for journals or trunnions 12 on the side of a lever 13; which lever may be in the form of a flat strip of metal having one end extending as a straight handle, and the other end bent inward and under to form an L-shaped cam tongue 15, located opposite and spaced from the axis of the trunnions.

The parts are so proportioned that when the handle of the lever is swung outward from the'base plate, the cam plate will be swung outward through the central opening therein, as shown by broken lines in Fig. 3; and that when the handle is swung inward parallel to the base plate, the cam plate will rotate inward through the opening into a position intermediate the base plate and abutment jaw 8 of the fastener.

For securing overlapping edge portions vided Vwith protrusions or other antisfrietion means, to me 1e securely hold the fabric of the cover; and the parts are so arranged that the angle of the L-eam plate must be forced Vbeyond a dead center by la compression of Y,the fabric or a yielding of the abutment jaw,V so that the elasticity of these parts serves to hold the cam lever in clamping position by pressin latwise against the elani in(T late i :a is v i abutment Jaw.

when the handle is swung inward, as Y:shown in Fig. 3. Y

YA fastener is provided on each edge of one overlapping end of the cover, and it is evident that the'correspending free edges of the underlapping end can be engaged in and clamped 'by the fastener at any place required foi an adjustment of the cover to neatly lit a tire; it being understood Vthat after entering the free edge under the abutment jaw, the edges may slide longitudinally upon each other, until a proper adjustment of the cover is attained, whereupon the cani lever is operated to clamp and secure the edges togetlier in the desired position of adjustment.

I claim:

l. A tire cover having overlapping ends with fasteners on the edges of one end for engaging Vand clamping Ythe corresponding edges of the other end.

2; A tire eover having overlapping ends with fasteners on the edges of one end having abutment jawsy for engaging the edges of the other end, and means for clamping the overlapping edges against the abutment law.

3. A tire cover having overlapping ends with fasteners on the edges of one end having abutment jaws Vfor engaging the edges of the other end, and a cani tongue fer clamping the'overlapping edges against the 4:. A' tire cover having overlapping ends with fastenerson the edges of one end, eae'h edge having an abutment jaw spaced from one side thereof, a cam tongue operatively mounted on the other side: thereof, for- Yfastener including a base plate secured to one
